Data

The {azores.fkw} bundles the main data sets needed to replicate the analysis in this R compendium. Data are provided as exported R objects:

• individuals: Photo-identified false killer whale individuals.
• sightings: False killer whale sighting events.
• boat_trips: Track data of boat while performing sightseeing in the Azores’ study region.
• boat_trips_by_min: An aggregated version of boat_trips by minute.
• ethology: Observed whale behaviors during each sighting.
• pod_age_composition: Pod age composition for each sighting.
• reaction_to_boat: Pod overall reactions to boat presence for each sighting.
• azores_islands: Azores islands as a simple feature (sf) object.
• azores_bathymetry: Depth values for the Azores region provided as a tibble.

Code

The whole analysis code used in the paper can be found at: https://www.github.com/patterninstitute/azores.fkw/tree/main/inst/opencr_analysis.

The R script opencr_analysis contains the analysis pipeline. This code itself either depends on published CRAN packages or on code from this R compendium itself.

The results have been cached as an RDS file and can be found in inst/opencr_analysis/opencr_results.rds.

Figures

The figures that result from the analysis can be found at https://www.github.com/patterninstitute/azores.fkw/tree/main/inst/opencr_analysis/figures. The code that generates them can be found in figures/figures.R.
